Filed: 1932-10-19
Abstract: 390,750. Gramophones. NYSTROM, C. W. 20, Ostra Torggatan, Karlstad, Sweden. Oct. 19, 1932, No.29251. Convention date, Oct. 19, 1931. [Class 40 (ii).] The arrangement described in Specification 385,807 for driving a turntable, so that the record is tracked by the recorder or reproducer at a constant speed, by a driven friction roll with peripheral ridges engaging a spirally grooved surface on the turntable or on a disc moving therewith, the driving roll being traversed radially by the grooved disc, is provided with means for disengaging the friction roll drive automatically at predetermined positions of the stylus in its traverse over the record. Transmission gear for moving the recorder or reproducer radially by, and in relation to, the radial movement of the friction roll is also provided. Figs. 1 and 2 show a turntable 61 connected with a disc 19 having a spiral groove on its underside engaged by a driven friction roll 27 slidable on a shaft 21 carried in a pivoted frame 23 which is supported with the roll 27 in contact with the disc 19 by a cam 47 acting through a spring 110. A bracket 63 movable with the roll 27 and carrying rollers 65, 65a riding on a rod 20 of the frame 23 is connected by links 83, 84 and an arm 85 with the vertical pivot 86 carrying the arm 90 and pick-up or recorder 91, which is thereby swung across the record as the roll traverses the disc 19. The record drive mav be arrested with the needle at various distances from the centre by means of a bell crank lever 71 pivoted on a slide 75 which is adjustable by a resilient arm 78 engaged in a notched plate 80. A roller 73 on one arm of the bell-crank extends under a bail 67 fixed to the spindle 68 of the cam 47, and a roller 74 on the other arm of the bellcrank extends into the path of the roller 65a on the bracket 63 and is engaged thereby after the predetermined traverse of the driving roll and the needle as set by the slide 75, thereby rocking the bell-crank and consequently the bail 67 and cam 47 so that the roll 27 is no longer supported in driving engagement. The Specification as open to inspection under Sect. 91 describes a modification in which the recorder or reproducer is traversed radially across the record by supporting it from a bracket which is moved along a guide rod by the sliding movement of the friction driving roll. This subject-matter does not appear in the Specification as accepted.

Abstract: 366,496. Making boxes. UNIVERSELLE CIGARETTENMASCHINENFABRIK J. C. MLLER & CO., 48, Zwickauerstrasse, Dresden, Germany. Sept. 30, 1930, No. 29289. Convention date, Oct. 1, 1929. [Class 18.] The process described in Specification 319,330, [Class 18, Boxes &c.], is modified for forming a box, Fig. 5, without a neck strip from a body blank and lid blank, the body blank having side flaps and extensions 1c, 1d, 1e thereon over which the lid flaps are adapted to engage and the blanks being together formed into a box-like structure in a shaping channel by means of a forming-block. The body blank 1, Figs. 2 and 3, and lid blank 2 are fed from opposite sides over the shaping channel 13, Fig. 1, and under the forming block 5 which is forced by a ram 10 against the overlapping parts 1a, 1e, 2b of the blanks and through the channel against a spring-controlled ram 101. Folding cheeks 11 turn the side flaps and extensions 1c, 1d against the block and cheeks 12 turn the flaps 2c, 2d thereover. The ram 10 then rises and a folding finger 17 folds down the wing 15 ; a ram 18 then forces the box-like structure through a shaping channel 35 where the wing 15<1> is folded down by a member 30 and cheeks 20 fold down the flaps 1b, 2a, the wings 15, 15<1> becoming fixed to adhesive parts 9a, 9b of the flap 1b. A ram 19 then forces the box against a gummed edge-closing strip 24 fed over a spring-controlled ram 31 at the entrance to a channel y, the downward movement of the rams causing the ends of the strip to be applied to the vertical sides of the box. The ram 19 then rises, a finger 32 turns down one projecting end of the strip on to the top side of the box and a ram 23 pushes the box into the brush-lined channel y, the upper edge of which folds down the remaining end of the strip 24. Catches 26 on a chain 25 then engage the box and carry it through a brush-lined channel z where knives 28 cut through the strip 24 at the narrow sides of the box which is then engaged by a chain 27 and carried past a knife 28<1> which cuts through the strip at the front of the box. Further movement of the box carries it past a tongue 37 which raises the lid at the front so that an inclined member 38 may completely open it. The block 5 is then removed by mechanical, pneumatic, magnetic or other means and raised by a ram 34 within range of a conveyer 41 which carries it towards the ram 10. The lid blank in its passage to the block 5 is curved by presser blocks 7, 8 and the side 14 of the channel 13 is pivoted and spring-controlled to accommodate the curved face of the block.

Abstract: 1,223,807. Optical position detector. INTERNATIONAL BUSINESS MACHNIES CORP. 11 June, 1969 [12 July, 1968], No. 29488/69. Heading H4D. [Also in Division H1] Specification describes an arrangement for determining the orthogonal co-ordinate position of a light pen 24, Fig. 1, over a display means 9. Said arrangement comprises a pulsed laser source 1 providing two beams of laser pulses 2 and 3 at slightly different pulse repetition periods. The parallel beams are diverged by cylindrical lenses 6 and 16 to cause each light path to travel as a circular wave front. The pulses intercept the circular edges 8 of a plate of photochromic glass 9, whereby the circular wave fronts are converted into straight wave fronts 10, 20 and 18, 21 travelling through the glass such that the locus of a cross over (coincidence) point 20, 21 of two orthogonal wave fronts, is line 23. Because of the slight difference in the periods of two light pulses, the locus of the next cross-over point, 10, 18 will be slightly displaced from, but parallel to, locus 23. The whole of display area 11 will thus eventually be raster scanned. The laser light is infra red and the light pen comprises, Fig. 4, a light guide 61 shining a beam of ultra-violet on area 11. This causes the photochromic glass to locally scatter the infra-red wave fronts. The increased scattered infra-red, caused by the passage of a wave front cross-over point, causes non-linear detectors 62, 63 to emit a pulse, which by its timing with respect to known reference times, gives the orthogonal co-ordinates of the pen. The plate 9 may alternately be a simple glass sheet with a light scattering ground surface. The ultra-violet illumination may then be dispensed with.
